Manager Danny Wilson is relieved after watching his Sheffield United side come from behind to secure a 3-1 win over Leyton Orient.
The win ensures the League One contenders stay four points clear of Sheffield Wednesday in second place.
Kevin Lisbie put the visitors ahead in the 12th minute following a long upfield punt from goalkeeper Jamie Jones before Lee Williamson's 42nd-minute equaliser after receiving the ball from Ched Evans.
Michael Doyle (54) struck from 20 yards to put the hosts in front and Evans (83) scored his 35th goal of the season as United chalked up their sixth straight victory, while Orient's Ryan Dickson was sent off in the 61st minute for a wild challenge on Williamson.
Wilson said: "I'm relieved to get three points because it was a very tight game. The three points is the important thing at this stage of the season. They were very determined and didn't make it easy for us. They then had a player sent-off, which was fully deserved.
"It wasn't an easy game by any stretch of the imagination, but we scored three terrific goals. We always look like we're going to score.
"Lee Williamson has had an outstanding season. The telepathy that he and Matt Lowton have is great. They link up very well and that right-hand side is very potent for us."
